Reamer Shoe Reamer shoe is a casing shoe that overcomes welbore obstructions to guide casing or liners to total depth (TD). The eccentric guide nose climbs ledges and negotiates obstructions while the cutting structure reams out tight spots or obstruction in the wellbore. Compatible with all casing and liner hanger assemblies, our Reamer Shoe provides highly effective protection- against unexpected or anticipated casing and liner running problems, and has been specifically designed for potentially difficult wellbore conditions such as swelling shales, ledges and washed out areas of wellbore. Features of our reamer shoe: API Standard Casing Reamer Shoe Tough durable profiled cement nose Fitted with High flow phenolic float valve tested in excess of API test procedures 5,000 & 10,000psi Valves Available Double Valve Option Available Autofill Option Available New and Improved cementing process for valve retention Cement tested to 5000 & 10,000psi Material: P-110, ...

China Crossover Sub Crossover Sub Product Details Crossover sub is mainly used to connect upper and lower drill tools in different connectors in drilling operations. Also it can be used to protect other tooling in drill stem (called saver sub ) or be used to deliver outgoing air to the bit face just above the bit (called bit sub). The length of crossover subs is generally measured from shoulder to shoulder. Typical lengths range from 6″ – 28″ long going up in increments of 2 inches with AISI 4145H, AISI 4145H Mod, AISI 4340, AISI 4140-4142 and Non-magnetic material. All connections are phosphate-coated or copper plated to improve resistance to corrosion.

What is a liner hanger We are liner hanger manufacture and supplier.We know the  liner hanger  is a very important part tools in oilfield drilling.So let us introduce more knowledge about liner hanger. First, what is a Liner Hanger? Liner Hanger is similar to casing, is a tool/system that is used to hang a liner in a production well. but it is not run through the full depth of the well, as casing is. A liner hanger allows the liner (casing below the liner hanger) to be suspended in the previous casing string to reduce material cost and provide completion solution options. A seal is required at the top of the liner hanger to prevent transfer of fluid or pressures from either direction. Liner hanger systems could be mechanical or hydraulic, premium or standard, rotating or non-rotating, conventional or expandable and pocket slip. Second,What is the usage of a Liner Hanger? The purpose of the liner hanger, aside from the structural well construction purpose already an...
